Description

User askes how to set the timeout on HBase connection; In his case, some query will report timeout error after 60 seconds, from their observation it need about 77 seconds to finish; They hope this timeout value can be customized;

Checked the code, in org.apache.kylin.common.util.HadoopUtil.newHBaseConfiguration(), there are some hard-coded configurations:

        // reduce rpc retry
        conf.set(HConstants.HBASE_CLIENT_PAUSE, "3000");
        conf.set(HConstants.HBASE_CLIENT_RETRIES_NUMBER, "5");
        conf.set(HConstants.HBASE_CLIENT_OPERATION_TIMEOUT, "60000");
